Using Elementary OS Luna Beta1 on kernel ???.33 installed amd-driver-installer-12.6-legacy-x86.x86_64.run and rebooted. after autologin to the desktop I did a software update check and cancelled, then i opened a terminal window and typed in aticonfig. Then I got the error window for this bug.... enough details? Good Luck. :)

Title differs a bit cause of different language server:
Title: update-apt-xapian-index crashed with IOError in __init__(): [Errno 2] No such file or directory: '/var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_precise-security_universe_i18n_Translation-en'
